Systems and Methods for Providing Lockless Bimodal Queues for Selective Packet Capture

3. The method of claim 1, further comprising determining whether the storage structure contains an unconsumed packet.

5. The method of claim 4, wherein inserting the one or more new packets into one or more occupied locations in the storage structure comprises retrieving and discarding one or more packets from the one or more occupied locations.

6. The method of claim 4, wherein inserting the one or more new packets into one or more occupied locations in the storage structure comprises overwriting one or more previously inserted packets in the one or more occupied locations.

7. The method of claim 1, wherein consuming the one or more unconsumed packets comprises one or more of: processing, forwarding, or storing the one or more unconsumed packets.

8. The method of claim 1, wherein the storage structure comprises a storage ring.

9. The method of claim 1, wherein the storage structure comprises a limited size storage structure, having a size from 1 kilobytes up to 10 gigabytes.

10. The method of claim 9, wherein the number of unconsumed packets retrieved and consumed by the consumer after the wake-up signal is received and before subsequently receiving any sleep signal is greater than the size of the storage structure.

14. The method of claim 1, wherein the shared memory location comprises a flag that indicates: (i) a mode transition of the producer and (ii) a mode transition of the consumer, the flag being controlled via a hardware-implemented, atomic compare-and-swap operation.

17. The system of claim 15, wherein the consumer process programs the processing unit to determine whether the storage structure contains an unconsumed packet.

19. The system of claim 18, wherein to insert the one or more new packets into one or more occupied locations in the storage structure, the producer process programs the processing unit to retrieve and discard one or more packets from the one or more occupied locations.

20. The system of claim 18, wherein to insert the one or more new packets into one or more occupied locations in the storage structure, the producer process programs the processing unit to overwrite one or more previously inserted packets in the one or more occupied locations.

21. The system of claim 15, wherein to consume the one or more unconsumed packets, the instructions program the processing unit to one or more of: process, forward, or store the one or more unconsumed packets.

22. The system of claim 15, wherein the storage structure comprises a storage ring.

23. The system of claim 15, wherein the storage structure comprises a limited size storage structure, having a size from 1 kilobytes up to 10 gigabytes.

24. The system of claim 23, wherein the number of unconsumed packets retrieved and consumed by the consumer process after the wake-up signal is received and before subsequently receiving any sleep signal is greater than the size of the storage structure.

28. The system of claim 15, wherein the shared memory location comprises a flag that indicates: (i) a mode transition of the producer and (ii) a mode transition of the consumer, the flag being controlled via a hardware-implemented, atomic compare-and-swap operation.
